Right temporal bone, os iemporale, from within. The pars mastoidea is a thick conical projection m^t well developed untU. adult life. Developmentally it is not an independent part of the bone, but a secondary outgrowth- from the lateral and most posterior part of the temporal bone and belongs actually in part to the pars petrosa and in part to the squama temporalis. Its posterior, serrated margin, margo occipitalis , comes into apposition with the margo mastoideus oss. occipitalis (sutura occipitomastoidea) ; the short upper serrated margin forms with the margo parietalis of the squama temporaUs an ang-ular indentation, the incisura parietalis, in which is received thi^ angulus mastoideus oss. parietalis (sutura parietomastoidea) ; ahovi^ and in front it goes over into the squama temporalis, in front it adjoins the pars tympanica; thi^ site of jimction of the two components is iadicated (often very incUstinctly in the adult) by the siitura squamosomastoidea which runs lateralward, obliquely do\vnward and fnvwiird. The lateral surface is convex and shghtly roughened (tor the attachment of the imu. auricularis posterinr et occipitalis), and often presents behind one or se\i'ral foramina mastoidea (for the ramus mastoideus a. occipitalis, emissarium maHtoiileuiu) which hih'u on the medial surface in the sulcus sigmoideus. Projecting lateralward from the posti'rior superior margin of th(> porus acusticus exte^rnus there is frequently found a small spur, the spina supra meatmn : the surface behind it, ottem
Bones of the Skull. 9 A thick process extending domiward, the processus mastoideus (for the attachment of the mm. sternocleidomastoideus, splenius capitis, longissimus capitis) presents on its medial surface, a smooth depression, the incisura mastoidea (0. T. digastric fossa) for the attachment of the digastric mnscle, and, further medianward, a groove, the sulcus arteriae occipitalis (for the a. o(-cipitalis). The medial surface of the pars mastoidea is fused in fi-ont with the pars petrosa ; behind, it is free and there presents a deep groove, the sulcus sigmoidevs (0. T. fossa sigmoidea) (for the sinus transversus). Inside the process are mam' cavities hned by mucous membrane, the cellulae mastoideae (cf. Fig. 11). The pars petrosa (pyramis) is a three-sided pyramid, the base of which is directed lateralward, and is united with the pars mastoidea. It presents for examination three surfaces, a fades posterior, a fades inferior and a fades anterior; at the jimctions of the surfaces are the anguhis posterior , the angulus anterior, and the angulus superior. The tip, or apex pyramidis , is directed medianward and forward, and is inserted in the angle between the occipital bone and the sphenoid bone, leaving, however, an irregular chink, the foramen lacerum which is fiUed by the fihrocartilago basalis. The fades posterior pyramidis almost vertical, is bounded above by the angulus superior with the sulcus petrosus superior (for the sinus petrosus superior ; tentorium cere- beUi), below by the angulus posterior; the latter is rough and unites with the lateral margin of the pars basUaris and the pans lateralis of the occipital bone ffissura and synchondrosis petrooccipitalis) , and contains above at the upper surface of this place of union the sulcus petrosus inferior (for the sinus petrosus inferior). At about the middle of the posterior surface a circular opening, the porus acusticus internus, leads into the short meatus acusticus intei-nus (for the a. and vv. auditivae internae ; nn. facialis and acusticus). Above and lateralward close to the superior angle hes the fossa subarcuata which, running below the superior semicircular canal, receives a process of the dura mater; this fossa, very well marked in the new-born (see Kg. 15), is usually only shghtly indicated in the adult. Still further lateralward and downward is seen the apertura externa aquaeductus vestibuli (for the ductus endo- lymphaticus); it is usually sHt-shaped, opening from a dorsolateral direction, and from it a gi-oove runs downward to the incisura jugularis. The fades inferior pyramidis is placed horizontally and is very uneven and rough. In front its boundary is formed laterally by the pars tympanica and medianward therefi'om by a ft-ee margin, the angulus anterior, which unites with the margin of the large wing of the sphenoid bone situated medianward from the spina angidaris, to form the fissura and synchondrosis sphenopetrosa. Behind it is bounded by the angulus posterior. A notch, sometimes scarcely noticeable, the incisura jugularis, close to the small processus intrajugularis, forms with the oon'esponding incisura jugularis of the occipital bone (p. 2), the foramen jugulare (lateral compartment for the v. jugularis interna; medial for the sinus petrosus inferior; nn. glossopharyngeus , vagus, accessorius, gangl. superius n. glossophar}Tigei , gangl. jugulare n. vagi). Just in fi-ont of this notch hes the broail fossa jugularis (for the bulbus v. jugularis superior) with a small hole, one of the openings of the canaliculus mastoideus, and a groove leading to this, the sulcus canaliculi mastoidei (for th(! r. auricularis n. vagi). Just medianward from the jugular fossa near the posterior angle, is seen a funnel-shaped depression, with the apertura externa canaliculi cochleae (for the v. canahculi cochleae).
